7 Claims.

This invention relates to improvements in locomotive tender frame and tank constructions, and more particularly to tender frames of the single longitudinal beam type broadly disclosed in the prior application of A. R. Ayers and G. S. Vail bearing Serial No. 548,802, filed July 6,1931. Among the objects of my invention is to pro vide an improved construction of tender frame of the type above mentioned, which will give increased water capacity and lower center of gravity of the tank. A. further object is to provide a simplified form of main frame casting which r quires less metal and lends itself more readily to the machining and casting processes, and wherein the cores may be more readily set for moulding, and the resulting casting may be more readily cleaned, than with prior frame designs used for a similar purpose.

proved construction and arrangement of the single longitudinal beam which forms the major portion of the frame wherein the bottom portion of said beam is widened to form a horizontal ledge along each side of said beam, which ledge forms a supporting surface for the bottom plates of the tank on a level intermediate the top and bottom of said beam.

I also provide the upper margins of the beam side plates with outwardly turned flanges, which strengthen the beam at this point, and at the same time promotes ease in handling the cores during casting and cleaning the interior of the casting after it is completed.

Other objects of the invention will appear from J time to time as the following description proceeds.

In the drawings,

Fig. 1 is a side View of a locomotive tender in eluding a tender frame constructed in accordance with my invention. N

Fig. 2 is a plan view of the tender frame employed in the tender shown in Fig. l.

Fig. 3 is a longitudinal section taken on 3-3 of Fig. 2.

Figs. 4a and 5 are enlarged detail sections taken line on lines as and 55, respectively, of Fig. 2, and

showing a portion of the tank superstructure.

Figs. 6, 7 and 8 are detail sections taken on lines 6-6, '7-'7 and 8--8 of Fig. 2, with the tank superstructure omitted. Fig. 9 is an enlarged detail section of the beam ledge and tank bottom plate joint.

Referring now to details shown in the drawings, the locomotive tender shown in Fig. 1 comprises a tank 10 supported on main frame 11, which in turn is supported on trucks 12, 12 which may be of any suitable construction. The tank 10 shown herein is of the usual two-compartment type, the rear compartment 10 being for water, and the front compartment 10 for coal. A third compartment 10 is shown beneath the coal com- In carrying out my invention, I provide an im- (e1. Mia-221 partment, which may be used as a stoker-well, or

additional water space.

The main frame 11 is generally of the type shown in the Ayers and Vail application, Serial No. 548,802, hereinbefore referred to, and consists of a centrally disposed, relatively narrow longitudinal beam 15 of hollow construction, and having a widened front end portion 16 of substantially the same width and length of the stoker-well space 10. The entire frame is pref erably cast in a single piece.

The frame is provided with the usual truck bearing 17 being integral with the central beam 15, and the front truck bearing 18 being integral with the widened beam portion 16 beneath the stoker-well. The frame is also provided with housings 15 and 16 for the usual draft connections (not shown) at the rear and front ends, respectively.

Referring now more particularly to the features of novelty forming the subject matter of the present application, the same is best illustrated in the several transverse sectional views of the mainframe and associated parts of the tank bottom appearing in Figs. 4 to 7, showing the improved form of beam section employed.

For instance, Fig. 5 shows a typical cross section of the central beam 15, from which it will appear that said beam consists of a bottom web or wall 20 and upright side walls each consisting of a lower portion 21, and an inwardly offset upper portion 22 connected by a substantially horizontal continuous wall portion 23. The latter portion forms, in effect, a ledge 24. extend ing along both sides of said beam 15 in a plane considerably below the upper surface thereof, and herein being slightly below the mid-point between theupper and lower surfaces of said beam; This ledge provides support for theinner edges of thetank bottom plates 25, as will hereinafter be more fully described.

The upper=eclges of side wall portions 22 are cross connected at intervals bycross supports 26, 26, which in the form shown carry raised pads 27, 27 for mounting parts of the tank super structure. The beam is also reinforced at intervals by upright interior cross webs 28, 28 which, as shown in Figs. 5 and 6, are preferably arranged in inclined'position from the bottom web to the side walls, and leaving substantial apertures 29, 29 adjacent the lower corners of the beam to permit the passage of water lengthwise of the latter.

The upper edges of side wall portions 22 are also reinforced by outwardly turned flanges 30, 30, disposed in the same plane as the cross sup-n ports 26 and forming therewith lateral extensions for the tank superstructure pads 2'4, 2'7. Said flanges are also reinforced at intervals by upright webs 31 on the exterior of the side wall portions 22, as shown in Fig. 6.

As will be seen in Figs. 7 and 8, the ledge 24 formed by offsetting the side walls of the beam 15, is continued along the side walls of the en-. larged portion 16, but owing to the fact that the laterally extended parts of said enlarged por-- is built up on the main beam by securing the bottom plates 25 along the ledges 24 and flanges 33 at each side of the main frame 11. As an especially convenient construction for welding the parts together, shown in detail in, Fig. 9, the ledge portion 24' has an upwardly inclined portion 23 adjacent the upper wall 22. The arrangement is such that when the edge of the tank bottom plate is placed on said ledge, an open channel is formed for receiving a welding bead as indicatedat 23!.

Core holes 35 and apertures 36; which may be formed. in the main frame bottom web 20 for convenience in casting, are closed up as by welding therein suitable plates 35 and 36, respectively, so that the body of said main frame forms a water-containing part: of the tankt-hroughout its length.

A plurality of apertures 3'7, 37 are formed in the upper wall portions 22 of beam 15 just above the ledge 24 to provide communication between the main body of the tank and the interior of the hollow main frame. Similar apertures 38; 38 are formed along the sides of the widened portion 16 above the flanges 33. With this arrangement, all of-the water from the tankmay be drained intothe center beam and carried forwardly therethrough to suitable drainage outlets 103, 103 leading from the bottom of the main beam adjacent the front coupling connection;

The tank superstructure is also supported upon the top of the main frame, as: by interior braces 40 mounted on-the raised pads 27', 2'7 on beam- 15, and on, similar pads; 27 27 suitably arranged' on the enlarged en'dfportiori 16. Since the tank superstructure and its interior' bracing means formno part of the present invention, detailed reference-thereto may be omitted From the above description, the following advantageous features will now be manifest-r The main beam 15 is widened'at its bottom so as to form supporting ledges for the tank bottomplate. and providean-increased' -water capacity with a lowered center of gravity, The-beam is formed of maximum-strength with a'minimum of metal. The upper flanges 30"are arranged to increase the effective width of the'tank superstructure pads 2'7, and together with the adja cent ledge 24 and side wall po'rtionQform in effect a channel section or beam of especialstrength. In fact, each side "Wall with the adjacent top flange and bottom" wall-portion, form in effect an S-shaped' beam section.

The arrangementof the top-flanges in out;- wardly turned position alsoxassistsgreatly in the setting of themolding cores, and furthermore renders the casting much easier to clean When completed.
